Hostas are among the most adaptable, easy-to-care-for perennials available. They do well from USDA Hardiness Zone 3 southward as far as zone 9.
Hostas are hardy in cold winters. In fact, hostas only need four to six weeks of temperatures below 40 degrees for the hostas to go dormant and get their winter sleep. There is no winter growth during this time like there is with some other perennials.
Many hosta varieties need no help to survive the winter months in all but the most extreme environments. Also, mature hostas will normally be fine through the winter.
First-year plants may need an extra layer of winter protection. A covering of leaves, straw or other biodegradable materials that are light and allow for air pockets are perfect.
If you have stored potted hostas in an unheated garage, greenhouse or shed for the winter, be sure to check the soil in the pots every other week and only water if the soil is completely dry to the point of being dusty.
Never water frozen soil. That can rot the roots.
Not much else to do with your hostas in the winter besides letting them rest up for another glorious spring!
